Machine, with all due respect I know you are passionate about this. However, you are simply wrong. Local municiplalities have the right to govern themselves, to create laws and enforce them.
In this case the Collinsivlle council simply states that the droopy ass revealing pants are indecent and not acceptable in a public setting. The are within their rights to do that. They can also access fines accordingly.
The chief is paid to enforce laws. If a stop sign is put up and he thinks it's b.s. he still has to ticket those who run the sign.
The constitution gives states the right to make their own laws and the states hand that authority to cities, towns and villages. It's the way it works.
Hopefully the hoosiers who wear their pants on the ground will snap to and not invoke the penalty.
